Aiming Adjustment
NKS001PO
The front fog lamp is a semi-sealed beam type which uses a replaceable halogen bulb. Before performing
aiming adjustment, make sure of the following.
●
Keep all tires inflated to correct pressure.
●
Place vehicle on level ground.
●
See that vehicle is unloaded (except for full levels of coolant, engine oil and fuel, and spare tire, jack, and
tools). Have the driver or equivalent weight placed in driver seat.
Adjust aiming in the vertical direction by turning the adjusting screw.
1.
Set the distance between the screen and the center of the front
fog lamp lens as shown at left.
2.
Turn front fog lamps ON.
3.
Adjust front fog lamps using adjusting screw so that the top edge
of the high intensity zone is in the hatched area as shown in the
figure.
●
When performing this adjustment, cover the headlamps and
the opposite front fog lamp, if necessary.

TURN SIGNAL OPERATION
LH Turn Signal Lamp
When the turn signal switch (combination switch) is in left position with the ignition switch in ON position, BCM
detects the TURN LH (ON) by combination switch reading function. BCM outputs the turn signal (LH) intermit-
tently, and BCM also sends the turn indicator signal (LH) intermittently through CAN communication. BCM
supplies power
●
through BCM terminal 45
●
to front combination lamp LH terminal 2, and
●
to rear combination lamp control unit terminal 3.
When receiving the turn signal (LH), rear combination lamp control unit detects the turn signal (LH) ON, then
rear combination lamp control unit outputs the rear combination lamp drive signal LH intermittently (turn signal
output). Rear combination lamp control unit supplies power
●
through rear combination lamp control unit terminal 5
●
to rear combination lamp LH terminal 1.
Ground is supplied
●
to front combination lamp LH terminal 8
●
through grounds E13, E26 and E28,
●
to rear combination lamp LH terminal 4
●
through rear combination lamp control unit terminal 13.
Unified meter and A/C amp. receives the turn indicator signal (LH) through CAN communication, then makes
turn signal indicator (LH) start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the flashing of the LH turn signal lamps.
RH Turn Signal Lamp
When the turn signal switch (combination switch) is in right position with the ignition switch in ON position,
BCM detects the TURN RH (ON) by combination switch reading function. BCM outputs the turn signal (RH)
intermittently, and BCM also sends the turn indicator signal (RH) intermittently through CAN communication.
BCM supplies power
●
through BCM terminal 46
●
to front combination lamp RH terminal 2, and
●
to rear combination lamp control unit terminal 4.
When receiving the turn signal (RH), rear combination lamp control unit detects the turn signal (RH) ON, then
rear combination lamp control unit outputs the rear combination lamp drive signal RH intermittently (turn signal
output). Rear combination lamp control unit supplies power
●
through rear combination lamp control unit terminal 7
●
to rear combination lamp RH terminal 1.
Ground is supplied
●
to front combination lamp RH terminal 8
●
through grounds E13, E26 and E28,
●
to rear combination lamp RH terminal 4
●
through rear combination lamp control unit terminal 14.
Unified meter and A/C amp. receives the turn indicator signal (RH) through CAN communication, then makes
turn signal indicator (RH) start flashing operation interlocked with the buzzer sounds in combination meter.
With power and ground supplied, BCM controls the flashing of the RH turn signal lamps.

TURN SIGNAL AND HAZARD WARNING LAMPS
Revision: 2006 August
2006 Murano
LED Cut Detect Function
LED circuit has 9 rows of parallel circuits with 3 LEDs* to 1 row and diagnosis circuit built in rear combination
lamp. Diagnosis circuit detects the state of rear combination lamp circuits and transmits the LED cut detect
signal to rear combination lamp control unit. Rear combination lamp control unit monitors the rear combination
lamp circuits via the LED cut detect signal during turn signal LH/RH operation. Then rear combination lamp
control unit judges the normality of rear combination lamp circuits and transmits the warning output signal (OK/
NG) to unified meter and A/C amp. Unified meter and A/C amp. transmits the LED burnout status signal (OK/
NG) to BCM through CAN communication depending on the warning output signal.
If BCM receives the LED burnout status signal (NG), BCM controls the high speed flashing during turn signal
LH/RH operation.
*: One of 9 circuits looks to have only 2 LEDs.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, combination meter detects hazard switch ON. Then combination
meter supplies ground
●
to BCM terminal 29
●
through combination meter terminal 9
When receiving the hazard switch signal, BCM detects the hazard switch signal ON. BCM outputs the turn sig-
nal (LH and RH) intermittently, and BCM also sends the turn indicator signal (LH and RH) intermittently
through CAN communication. BCM supplies power
●
through BCM terminal 45
●
to front combination lamp LH terminal 2
●
to rear combination lamp control unit terminal 3,
●
through BCM terminal 46
●
to front combination lamp RH terminal 2
●
to rear combination lamp control unit terminal 4.
When receiving the turn signal (LH and RH), rear combination lamp control unit detects the turn signal (LH and
RH) ON, then rear combination lamp control unit outputs the rear combination lamp drive signal LH and RH
intermittently (hazard output). Rear combination lamp control unit supplies power
●
through rear combination lamp control unit terminal 5
●
to rear combination lamp LH terminal 1,
●
through rear combination lamp control unit terminal 7
●
to rear combination lamp RH terminal 1.
Ground is supplied
●
to front combination lamp RH and LH terminals 8
●
through grounds E13, E26 and E28,
●
to rear combination lamp LH terminal 4
●
through rear combination lamp control unit terminal 13,
●
to rear combination lamp RH terminal 4
●
through rear combination lamp control unit terminal 14.
Unified meter and A/C amp. receives the turn indicator signal (LH and RH) through CAN communication, then
makes turn signal indicator (LH and RH) start flashing operation interlocked with the buzzer sounds in combi-
nation meter.
With power and ground supplied, BCM controls the flashing of the hazard lamps.

INTERLOCKED HAZARD LAMP OPERATION WITH REMOTE KEYLESS ENTRY SYSTEM
BCM receives the keyfob signal (door lock/unlock signal) from remote keyless entry receiver, then BCM con-
trols hazard lamps.
Refer to
BL-58, "REMOTE KEYLESS ENTRY SYSTEM"
INTERLOCKED HAZARD LAMP OPERATION WITH INTELLIGENT KEY SYSTEM
BCM receives the door lock/unlock signal from Intelligent Key unit through CAN communication, then BCM
controls hazard lamps.

CAN Communication System Description
NKS001PT
CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
